Experiences Building and Deploying Wireless Sensor Nodes for the Arctic Tundra [PDF]

, 2021
The arctic tundra is most sensitive to climate change. The change can be quantified from observations of the fauna, flora and weather conditions. To do observations at sufficient spatial and temporal resolution, ground-based observation nodes with ...

The changing carbon balance of tundra ecosystems: results from a vertically-resolved peatland biosphere model

Environmental Research Letters, 2021
An estimated 1700 Pg of carbon is frozen in the Arctic permafrost and the fate of this carbon is unclear because of the complex interaction of biophysical, ecological and biogeochemical processes that govern the Arctic carbon budget.

Инициальное почвообразование в Прибрежной Антарктике: существуют ли не орнитогенные почвы?

Український антарктичний журнал, 2017
Примитивные тундровые почвы сформировались и функционируют в суровых климатиче­ских условиях. Их изучение позволяет количественно оценить инициальные стадии почвообразова­ния, что крайне важно как для понимания процесса в целом, так и для создания ...

Vegetation, topography and snow melt at the Forest-Tundra Ecotone in arctic Europe: a study using synthetic aperture radar [PDF]

, 2003
This research was conducted as part of DART (Dynamic Response of the Forest-Tundra Ecotone to Environmental Change), a four year (1998-2002) European Commission funded international programme of research addressing the potential dynamic response of the ...

Spatial patterns of goose grubbing suggest elevated grubbing in dry habitats linked to early snowmelt [PDF]

Polar Research, 2013
The western Palaearctic tundra is a breeding habitat for large populations of European geese. After their arrival in spring, pink-footed geese (Anser brachyrhynchus) forage extensively on below-ground plant parts, using a feeding technique called ...

The modeled effects of fire on carbon balance and vegetation abundance in Alaskan tundra [PDF]

, 2012
Arctic climate is warming at a rate disproportionately faster than the rest of the world. Changes have been observed within the tundra that are attributed to this trend, including active layer thickening, shrubland expansion, and increases in fire ...

Patterned-ground facilitates shrub expansion in Low Arctic tundra

Environmental Research Letters, 2013
Recent expansion of tall shrubs in Low Arctic tundra is widely seen as a response to climate warming, but shrubification is not occurring as a simple function of regional climate trends.

Hydrologic Controls on Peat Permafrost and Carbon Processes: New Insights From Past and Future Modeling

Frontiers in Environmental Science, 2022
Soil carbon (C) in permafrost peatlands is vulnerable to decomposition with thaw under a warming climate. The amount and form of C loss likely depends on the site hydrology following permafrost thaw, but antecedent conditions during peat accumulation are

Soil nutrient content dominates short-term vegetation changes in alpine tundra of Changbai Mountains

Frontiers in Microbiology
Alpine tundra, covering 3% of the Earth’s land surface, harbors approximately 4% of higher plant species. Changes in this vegetation significantly impact biodiversity and ecosystem services.
